Can a planet not be a sphere?

How come there’s no CUUUBEah planets? Maybe even a Millennium Puzzle world, Omega LoL

[SnowedIn]

Serious question? If so, it's because they're forming while turning on their own axis and on a path around their star: you can't make a cube that way

Joke question? Because the Pokemon folks beat the D&D people and got to use spheres for planets instead of cubes.

WHERE IS THA CUUUUUBah?

[NamerOfStars]

Yes- but not for very long. Nature will, over time, tend towards the most efficient path.

[Dinosaursandanime65]

So no cube world?

[NamerOfStars]

No. You might get a bit of a triangle, but that's about it. The way planets form is by gathering matter ejected from stellar explosions together through gravity, and the spinning, over time, will wear down any projections. Remember that every single point on a sphere is equidistant from the center.

What would need to happen for a world to be a cube?

[NamerOfStars]

A very strange set of astronomic conditions. Or artificial engineering, if you're not picky about it being natural.

[Dinosaursandanime65]

If a planet in a solar system was a triangle, would all of the others be too?

[NamerOfStars]

No. To have it happen naturally, you'd need a strong enough pull of gravity in *multiple* directions to counteract rotational erosion- or just something so strongly locked that it didn't rotate relative to THOSE things that were pulling on it; the odds of something being in an orbit like that are low, in a STABLE orbit like that, almost nonexistent.

If it was not a sphere it would not have enough mass to be a planet.
